<Note 6> Speed Error Hold:
Default setting is "Disable". If you choose the setting to "Enable",
when CPU speed setting is wrong, then system will hold.
Normally, we do not recommend that you use the "User Define" option to setup
CPU speed and multiplier factor. This option is for setup of future CPUs whose
specifications are still unknown. The specifications of all present CPUs are
included in the default settings. Unless you are very familiar with all CPU
parameters, it is very easy to make mistakes when you define by yourself the
external clock and the multiplier factor.
Solution in case of booting problem due to invalid clock setup:
Normally, if the CPU clock setup is wrong, you will not be able to boot. In this
case, turn the system off than on again. The CPU will automatically use its
standard parameters to boot. You can then enter BIOS Setup again and set up
the CPU clock.
If you can't enter BIOS setup , you must try turning the system on a few times
(3~4 times) or press " INSERT " key when turn on and the system will
automatically use its standard parameters to boot. You can then enter BIOS
SETUP again and set up the new parameters.
When you change your CPU:
The motherboard have been designed in such a way that you can turn the system
on after having inserted the CPU in the socket without having to configure any
jumpers or DIP switches. But if you change your CPU, normally, you just have
to turn off the power supply, change the CPU and then, set up the CPU
parameters through CPU SOFT MENU

two methods to successfully complete the CPU change operation.
Method 1: Setup up the CPU for the lowest speed for its brand.
Method 2: Since you have to open the computer case when you

CCMOS jumper to erase the parameters of the
original CPU and to enter BIOS Setup to set up CPU
parameters again.
